Captain Apollo

This article ("13 Little Things NASA Did to Get Alan Shepard Ready for Space") from The Atlantic was new to me including the titbit that:

The Mercury astronauts had their electrode attachment locations tattooed onto their bodies! "The sensor locations have been previously marked on all Mercury pilots by the use of a tiny (about 2 millimeters in diameter) tattooed dot at each of the four electrode sites."

I wonder if it was done the way it's sometimes done with patients undergoing radiation therapy: once the targets are established, they'll tattoo targeting/alignment points by pricking the skin with a pin and applying a drop of permanent ink. (At least, that's how they did it in my case.)
